也可以试试这些(IE8 + Chrome。我不知道FF):

function addEvent(obj, type, fn) {
    eval('obj.on'+type+'=fn');
}

function removeEvent(obj, type) {
    eval('obj.on'+type+'=null');
}

// Use :

function someFunction (someArg) {alert(someArg);}

var object=document.getElementById('somObject_id') ;
var someArg="Hi there !";
var func=function(){someFunction (someArg)};

// mouseover is inactive
addEvent (object, 'mouseover', func);
// mouseover is now active
addEvent (object, 'mouseover');
// mouseover is inactive

希望没有拼写错误:-)

function. prototype.bind()是将目标函数绑定到特定作用域并可选地在目标函数中定义this对象的方法。

someObj.addEventListener("click", some_function.bind(this), false);

或者捕获一些词法范围，例如在循环中:

someObj.addEventListener("click", some_function.bind(this, arg1, arg2), false);

最后，如果目标函数中不需要this参数:

someObj.addEventListener("click", some_function.bind(null, arg1, arg2), false);

另一种解决方法是使用数据属性

function func(){
    console.log(this.dataset.someVar);
    div.removeEventListener("click", func);
}
    
var div = document.getElementById("some-div");
div.setAttribute("data-some-var", "hello");
div.addEventListener("click", func);

这里还有另一种方法(它在for循环中工作):

var someVar = some_other_function();
someObj.addEventListener("click", 

function(theVar){
    return function(){some_function(theVar)};
}(someVar),

false);

    $form.addEventListener('submit', save.bind(null, data, keyword, $name.value, myStemComment));
    function save(data, keyword, name, comment, event) {

这就是我如何正确地传递事件。
